So everything is on default and my game is running super smoothly. Constant 60FPS. The voice acting seems to be regular speed also, however the BGM is around 1.25x speed, maybe 1.5x speed and I'm not sure how I should fix it.

The game is Tenshi no Present: Marl Ōkoku Monogatari (天使のプレゼント マール王国物語)

Any help?

New here, so sorry if I'm posting on the wrong thread. There's so much!
